Abstract

In tight sandstone reservoir,diagenesis ultimately determines the performance of the reservoir.The quantitative evaluation of diagenetic reservoir facies and its relationship with distribution of high-quality reservoir is particularly important in reservoir evaluation.Based on the research of diagenetic reservoir facies feature of the He 8-1 in the tight gas reservoir of eastern SULG area,it clarified that the type Ⅰ,type II of diagenetic reservoir facies can reflect the geology characteristic of the quality reservoir formation of tight sandstone which can be the “sweet spot” to filter the relatively beneficial reservoirs.A comprehensive evaluation system of diagenetic reservoir facies logging multi-parameter quantitative classification was established based on the comprehensive analysis and evaluation results of the logging response characteristics and parameter sensitivity of different diagenetic reservoir facies types by core identification.By using Grey Theory Integration and some related analytial technologies,the diagenetic reservoir facies and relative high-quality reservoir “sweet spot” of tight gas reservoir could be quantitatively evaluated and classified with logging data.The scale and scope of the favorable gas reservoir in this north-south meandering river delta plain of He 8-1 were identified with the beneficial reservoir filtered before,which presented the distribution pattern,extension direction and heterogeneity of the beneficial gas reservoir of this tight gas reservoir.All of these can provide a target potential well and area for oil recovery.
